The present invention relates to a method and an apparatus for transmitting/receiving data, and a method for a user equipment transmitting data, according to one embodiment of the present invention, comprises: a step of determining conditions for determining whether a condition for transmitting short data is satisfied, when data to be transmitted is generated; and a step of including the data to be transmitted in a radio resource control (RRC) connection setup completion message and transmitting same, when the condition for transmitting the short data is satisfied. According to one embodiment of the present invention, the problem of network overload can be prevented by reducing signaling overhead when processing small packets, which are generated intermittently, in the mobile communication system, and an apparatus and a method for enhancing battery performance in the user equipment can be effectively provided.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method performed by a terminal in a wireless communication system, the method comprising: identifying whether uplink data occurs or not; determining whether a terminal is in an idle state or not; and transmitting, to a base station, a message associated with a radio resource control (RRC) including a non-access stratum (NAS) message, in case that the uplink data occurs and the terminal is in the idle state, wherein the NAS message includes the uplink data, and wherein the NAS message is integrity protected and the uplink data included in the NAS message is ciphered.
2. The method of claim 1 , wherein the idle state is a connection management idle (CM-IDLE) state.
3. The method of claim 1 , wherein the message is for confirming a completion of an RRC procedure.
4. The method of claim 1 , wherein the message further comprises core network entity information, and wherein the core network entity information comprises routing information for determining a core network entity to which the base station routes the NAS message.
5. The method of claim 1 , wherein the message is transmitted in case that a predefined condition is fulfilled.
6. A terminal in a wireless communication system, the terminal comprising: a transceiver; and at least one processor configured to: identify whether uplink data occurs or not, determine whether a terminal is in an idle state or not, and transmit, to a base station via the transceiver, a message associated with a radio resource control (RRC) including a non-access stratum (NAS) message, in case that the uplink data occurs and the terminal is in the idle state, wherein the NAS message includes the uplink data, and wherein the NAS message is integrity protected and the uplink data included in the NAS message is ciphered.
7. The terminal of claim 6 , wherein the idle state is a connection management idle (CM-IDLE) state.
8. The terminal of claim 6 , wherein the message is for confirming a completion of an RRC procedure.
9. The terminal of claim 6 , wherein the message further comprises core network entity information, and wherein the core network entity information comprises routing information for determining a core network entity to which the base station routes the NAS message.
10. The terminal of claim 6 , wherein the message is transmitted in case that a predefined condition is fulfilled.
11. A method performed by a network device in a wireless communication system, the method comprising: receiving, from a terminal, a message associated with a radio resource control (RRC) including a non-access stratum (NAS) message, in case that uplink data occurs and the terminal is in an idle state, wherein the NAS message includes the uplink data; and transmitting, to a core network entity, the NAS message including the uplink data, wherein the NAS message is integrity protected and the uplink data included in the NAS message is ciphered.
12. The method of claim 11 , wherein the idle state is a connection management idle (CM-IDLE) state.
13. The method of claim 11 , wherein the message is for confirming a completion of an RRC procedure.
14. The method of claim 11 , wherein the message further comprises core network entity information.
15. A network device in a wireless communication system, the network device comprising: a transceiver; and at least one processor configured to: receive, from a terminal via the transceiver, a message associated with a radio resource control (RRC) including a non-access stratum (NAS) message, in case that uplink data occurs and the terminal is in an idle state, wherein the NAS message includes the uplink data, and transmit, to a core network entity via the transceiver, the NAS message including the uplink data, wherein the NAS message is integrity protected and the uplink data included in the NAS message is ciphered.
16. The network device of claim 15 , wherein the idle state is a connection management idle (CM-IDLE) state.
17. The network device of claim 15 , wherein the message is for confirming a completion of an RRC procedure.
18. The network device of claim 15 , wherein the message further comprises core network entity information.
